Whenever we bite down, we’re applying force with our jaw muscles. Functional appliances direct these forces to create healthier tooth and jaw alignment. They’re used to help correct bite problems and to encourage symmetrical jaw growth.

Functional appliances aren’t always necessary. Because every child’s teeth and bite are different, orthodontic treatment at our Peoria, AZ office is carefully tailored to your child’s individual needs.

• For the child with minor tooth misalignment, traditional braces or aligners might be all that’s needed.
• For the child with a minor malocclusion, or bite problem, an orthodontist might use elastics (rubber bands) to bring teeth into healthy alignment.
• For the child who has a more serious malocclusion, involving both tooth and jaw alignment, an orthodontist might recommend a functional appliance.

A severe Class II malocclusion can be caused when the upper jaw or teeth are positioned too far forward, and/or the lower jaw is too small or positioned too far back. Common Class II malocclusions include:

• Open bite—the front teeth don’t touch when the back teeth bite down, or the back teeth don’t touch when the front teeth close.
• Overbite—some overbite is normal. A deep overbite occurs when the upper teeth significantly overlap the lower teeth.
• Overjet—the upper front teeth protrude further horizontally than they should.

Today’s functional appliances come in a variety of designs to treat Class II malocclusions. They can be fixed or removable. They can be used with or without braces. Some are designed to expand the upper palate to make sure there’s room for all the permanent teeth. What they all do is advance the position of the lower teeth and jaw to create a healthier, more comfortable bite.

Fixed devices are attached to the teeth and meant to be used full-time. These include the Forsus™ device, the Herbst® appliance, and the MARA appliance.

• Forsus Device

This appliance works with braces. A spring coil rod is most often attached to bands on the first molars on the upper jaw. It’s then connected to the arch wire on the lower jaw. Just like elastics—but more effective!—these spring coil rods provide gentle forward pressure that encourages the lower jaw and teeth forward.  

• Herbst Appliance

The Herbst appliance also applies forward pressure to the lower jaw using telescoping rods connecting the upper and lower teeth. The rods expand as the mouth opens, and telescope together as it closes, positioning the lower jaw further forward while the upper jaw is held back. The Herbst can be worn alone or with braces, and can also be used to expand the upper palate.

• MARA Appliance

The MARA (Mandibular Anterior Repositioning Appliance) uses an adjustable “elbow” piece connecting bands on upper and lower molars to guide the lower jaw and teeth forward when the jaw closes.

Removable appliances such as Bionator and Twin Block appliances can also improve Class II malocclusions. They are meant to be worn for a specific number of hours each day, and can be taken out for sports or other activities as needed. Because it’s essential to get all the necessary hours in, removable appliances require commitment!

• Bionators

A bionator is made of wire and acrylic, and it looks a lot like a retainer. The wire fits around the upper front teeth. It’s attached to a smooth piece of acrylic that sits behind the upper teeth and is shaped to guide the lower jaw forward when biting down. The bionator can also be adjusted to expand the upper palate.

• Twin Block Appliance

The twin block appliance uses two separate pieces made of wire and smooth acrylic. Both pieces are modeled to fit precisely over the upper and lower arches. The acrylic “blocks” fit over the biting surfaces of the teeth, working together like a 3D puzzle. When your child bites down, the upper blocks slide into place behind the lower blocks, pushing the lower jaw and teeth forward. The top plate can also be adjusted to expand the upper palate if needed.

Because these appliances are best used while a child’s bones are still growing and developing, dentists and orthodontists recommend an orthodontic evaluation by age seven. Early treatment with a functional appliance can help correct serious bite problems before or together with braces. In some cases, functional appliances may reduce the need for headgear or surgery.

Todays’ orthodontic technology has made functional appliances more comfortable and efficient than ever before. Talk to Dr. Thomas Shipley to discover how an individualized treatment plan and a custom appliance can give your child a healthy bite and a lasting smile.

The Shipley Orthodontics team knows that oral hygiene is important, whether you have braces on your teeth or not. But if you are a person who wears braces, caring for your teeth and gums can become somewhat challenging. Without daily oral hygiene practices, you may become prone to cavities and tooth decay during your time in braces.

Naturally, you know that brushing your teeth each morning and night, as well as after you eat, will help keep your mouth healthy and clean during the months you wear braces. But flossing is also an important part of your hygiene routine. Flossing with braces can be tricky, but it’s not impossible. Dr. Thomas Shipley, your general dentist, or your dental hygienist can help you become more comfortable and adept at flossing your teeth during the months you wear braces.

Flossing Tips for Those with Braces

• Use Tools Provided by Our Office. A floss threader is a small, plastic needle that will help you floss between the wires and your teeth. Thread a 12-to-18-inch piece of floss onto the needle, and use the needle to get the floss easily behind the wires.
• Flossing Under the Wires. Once the floss is behind the wires, use your hands to manipulate the floss. Move it up and down along the wires to remove food particles.
• Flossing Between Your Teeth. Floss between your teeth as you normally would without braces. Move the floss up and down between your teeth, using a clean section of floss for each tooth.
• After You Finish Flossing. Your orthodontist may have suggested that you use a water pik or proxy brush after you finish brushing. Either of these tools will help remove any loosened food particles to ensure that your teeth and braces are clean.

Continue Good Oral Hygiene Habits

Good oral hygiene habits you use while wearing braces will help you achieve the beautiful smile you and the Shipley Orthodontics team have been working toward. Once your braces are off, it may be tempting to slack off on the brushing and flossing. Don’t let yourself fall into any habits that will have a negative impact on your oral health or the attractive smile you waited for throughout the months you wore braces. See your general dentist for regular cleanings, and continue to brush and floss your teeth each day.

If you were to put your toothbrush bristles under a high-powered microscope, what you would see might give you nightmares: millions of bacteria, busily crawling up and down your toothbrush bristles, consuming proteins that came from your mouth, and still clinging to the bristles even after you’ve rinsed them with water.

Rinsing your toothbrush after brushing removes some of those ferociously hungry bacteria, but not all. The American Dental Association says that bacterial infestations develop on toothbrushes within a month of daily use. The ADA also states that unless a toothbrush is sterilized before being packaged, it’s going to come with bacteria – free of charge!

Germs and Frayed Bristles: the Demise of a Toothbrush

Dr. Thomas Shipley and our staff recommend that you toss your old toothbrush in the trash and purchase a new one every three months. Children tend to bite on their toothbrushes, which makes the bristles degrade and fray faster. Chances are kids may need to have their toothbrushes changed more frequently.

Where do they hide?

Bacteria are tenacious little germs that head for those concealed areas between toothbrush bristles. They are highly adaptable and exist in every type of extreme environment. Some people actually go so far as to put their toothbrush in a microwave for a few seconds to kill germs, but this doesn't always work either. In fact, you may only end up with a toothbrush that’s as bendable as a Gumby doll – and still covered with germs.

Feed a Cold, Starve a Fever, and Get Rid of Your Toothbrush

When you have a head cold, your mouth is teeming with bacteria gleefully roaming around, and gobbling mucus and dead skin cells. If you brush your teeth while suffering a sinus condition, the brush will act like a magnet for ravenous bacteria. Use your old toothbrush while you are sick, but as soon as you feel better, throw it away and get a new one. Otherwise you could possibly re-infect yourself with the same cold germs!

Your beaming smile makes a sunny day even brighter—and that sunny day can return the favor! How does the sun affect your dental health? Let’s shine some light on the subject.

You may have heard how important calcium is to your body. Over 99% of the calcium in our bodies is used to form teeth and bones, providing strength and structure to the hardest parts of the body. But that’s not the only task on the calcium to-do list. Calcium is also necessary for:

• muscles to work
• nerves to carry messages
• blood to deliver nutrients and oxygen
• the release of hormones

When we don’t get enough calcium in our diets, our bodies start to draw the calcium they need for these critical functions from our teeth and bones. Over time, a severe calcium deficiency can lead to teeth that are brittle, or more vulnerable to decay, or loose due to weakened bone density in the jaw.

Keeping up with your calcium is especially important when you’re wearing braces or aligners. Calcium helps protect you from tooth decay and gum disease, which could delay your treatment. And you want your jaw bones strong and healthy as the bone tissue reforms and then stabilizes around your teeth as they move to their new, ideal positions.

We can get the calcium we need from a balanced diet. Dairy products are our most common source of calcium, and several servings of milk, cheese, or yogurt each day supply most of our needs. If dairy’s not on your menu, though, you can get calcium from other foods like broccoli, kale, collard greens, canned salmon, or sardines. Because calcium is so essential to our health, many foods are fortified with it, including fortified juices, bread, cereals—even tofu!

But there’s a snag here, and it’s a big one. We can’t really benefit from our careful consumption of calcium without the help of vitamin D. If calcium is the doorway to strong teeth and bones, vitamin D is the key which unlocks all of calcium’s benefits.

Without enough vitamin D, our bodies can’t absorb and make use of calcium. However, getting enough of this essential vitamin can be a problem. While we can get most of the vitamins we need from a balanced diet, there aren’t a lot of foods which are naturally rich in vitamin D.

So, how do we get this vital vitamin? The original option comes from nature.

• Sunlight

Vitamin D is called “the sunshine vitamin” because of the unique chemical reaction which creates it. When the ultraviolet B rays of the sun reach special cells in our skin, they convert cholesterol in these cells to a basic form of vitamin D. These vitamin molecules travel through the body, picking up hydrogen and oxygen molecules in the liver and kidneys to become active vitamin D.

Since sunlight exposure is easy, available, and free, it seems like a simple solution to getting the vitamin D we need.

But we’ve understandably moved away from the days of basking in the sun for hours at a time. Over-exposure to UV rays damages the skin, causing premature aging and, worse, a much greater risk of skin cancer. If you enjoy time in the sun, talk to your doctor about safe sun exposure, which can depend on the part of the country you live in, the time of year, and your individual skin type.

And, if you need to avoid sun exposure, there are other opportunities for getting the vitamin D you need.

• Diet

While there aren’t a lot of foods which are naturally rich in vitamin D, there are still a few options on the menu. Oily fish like salmon, tuna, and herring—and old-fashioned cod liver oil—are good sources of the vitamin. But most of us don’t live on a strict fish diet!

Instead, we can get the vitamin D we need from fortified foods. Vitamin D is commonly added to cow’s milk, soy milk, orange juice, and cereals to make sure the calcium in our diet is working effectively to keep our teeth and bones strong. Check out nutritional labels to discover whether your favorite grocery products contain vitamin D. And don’t forget to choose foods that are braces-friendly, as well!

• Supplements

For hundreds of years, people who lived in climates and cities without a lot of sunshine suffered from the effects of vitamin D deficiency. Diseases like rickets, where the teeth and bones don’t form properly, were common in children. Adults who couldn’t absorb enough calcium suffered from weak teeth and bones.

Today, depending on age, allergies to sun or food products, dietary choices, and health conditions, some people are still at risk for vitamin D deficiency. If you’ve been diagnosed with this deficiency, your doctor might recommend a vitamin D supplement. (It’s important to take any supplement as directed, because taking too much vitamin D can be harmful, too.)

So, which form of vitamin D is best? Fortified foods? Supplements? Or is it that radiant original source—the sun? No need to worry. With any form of vitamin D, you’re getting the key you need to unlock the benefits of the calcium in your diet—for healthy teeth and bones before, during, and after your treatment at our Peoria, AZ orthodontic office. Your sunny smile will thank you!
